We've been watching Bethesda's countdown clock for the past day and today at 3PM, it's finally hit zero.

The first trailer for Fallout 4 has gone online. Without further ado, here it is.

So, reactions? We're guessing that the dog will be a big feature in it, either controlling him or perhaps playing him in certain missions.

The transition between pre and post nuclear fallout is interesting, which leads us to believe that the story is either split between them.

OR it could simply mean that it's the opening sequence, much like in Fallout 3, where you select your character based on who gets into the vault and so on.

Either way, we're damn excited. There's been no release date as of yet, but it's confirmed for PS4, XboxOne and PC.
